  1. What is a VMware virtual switch?
    A virtual switch is a software construct, implemented in the VMkernel, that provides networking connectivity for an ESX/ESXi host, directs network traffic between virtual machines and links to external networks.
  2. What is the fundamental component of a VMware virtual network?
    A virtual switch.
  3. What VMware network component allows connections for the management network on ESXi hosts and for the service console on ESX hosts.
    A virtual switch.
  4. At what layer of the OSI model do virtual switches work?
    Virtual switches work at layer 2 of the OSI model.
  5. A virtual switch can be configured to handle physical NIC failover. True or False?

    If False, Why?
    True.
  6. How can you have two virtual switches mapped to the same physical NIC?
    You cannot have two virtual switches mapped to the same physical NIC.
  7. You can have two or more physical NICs mapped to the same virtual switch. True or False?

    If False, Why?
    True.
  8. When two or more virtual machines are connected to the same virtual switch, how is network traffic routed among them?
    Traffic among them is routed locally.
  9. How can virtual machines connected to a virtual switch access the physical external network?
    If an uplink adpater is attached to the virtual switch, each virtual machine can access the physical external network that the adapter is connected to.
  10. A virtual switch provides 3 types of connections to hosts and virtual machines. What are the 3 connection types?
    • 1. VMkernel port:
    • . For example, IP storage or vMotion migraton
    • . For the ESXi management network
    • 2. One or more virtual machine port groups
    • 3. Service console port (ESX)
  11. What does a vSwitch virtual machine port group connection type provide virtual machines connections to?
    Virtual machine port groups provide virtual machines connections to locally attached virtual machines, external virtual machines (on other hosts) and physical networks.
  12. What vSwitch port provides the "ESXi management network" connectivity to network or remote services, including the VMware vShpere Client?
    The VMkernel port.
  13. What vSwitch port provides ESX connectivity to network or remote services, including the VMware vShpere Client?
    The service console port.
  14. Name at least 3 VMkernel services that a vSwitch connects to the physical network.
    • 1. IP Storage
    • 2. Distributed services eg. VMware vMotion migrations
    • 3. management network access for an ESXi host.
  15. What vSwitch connection types are set up by default during a ESX installation?
    • 1. Service console port.
    • 2. Virtual machine port group named VM Network.
  16. What vSwitch connection types are set up by default during a ESXi installation?
    • 1. VMkernel port named "Management Network".
    • 2. Virtual machine port group named VM Network.
  17. The VMkernel port and the ESXi management network port on a ESXi host share the same IP stacks. True or False?

    If False, Why?
    False.

    Separate IP stacks are configured for each. Each VMkernel port and ESXi management network port on a ESXi host must be configured with its own IP address, netmask and gateway.
  18. Separate IP stacks are configured for each VMkernel port and the service console port on a ESX host. True or False?

    If False, Why?
    True.

    Each VMkernel port and service console port on a ESX host must be configured with its own IP address, netmask and gateway.
  19. How do the virtual machine port groups, VMkernel ports and the service console port connect to the outside world?
    The virtual machine port groups, VMkernel ports and the service console port connect to the outside world through the physical Ethernet adapters that are connected to the vSwitch uplink ports.
  20. More than one network can not exist on the same virtual switch. True or False?

    If False, Why?
    False.

    vSphere allows you to place all your networks on a single virtual switch. Or you can use mulitple virtual switches, each with a separate network - the decision partly depends on your physical network layout.
  21. How can you isolate networks on a single virtual switch?
    You can isolate networks by using VLANS.

    For examlple, you can use less network adapters by teaming NICs in a single virtual switch and isolating the networks with VLANs.
  22. At what level are physical NICs assigned in a vNetwork?
    Physical NICS are assigned at the virtual switch level.
  23. All ports and port groups defined for aparticular virtual switch share the same hardware. True or False?

    If False, Why?
    True.
  24. Name the types of virtual switches a vSphere 4.1 vNetwork supports.
    • 1. vNetwork standard switch
    • Virtual switch configuration at the host level.

    • 2. vNetwork distributed switch
    • Virtual switch configuration at the VMware vCenter Server level.
  25. How many type of virtual switches does a vSphere 4.1 vNetwork support?
    A vSphere 4.1 vNetwork supports two kinds of virtual switches.

    • 1. vNetwork standard switch
    • Virtual switch configuration at the host level.

    • 2. vNetwork distributed switch
    • Virtual switch configuration at the VMware vCenter Server level.
  26. What is the maximum virtual switch ports per standard virtual switch?
    4,088 virtual switch ports.
  27. What is the maximum virtual switch ports per host?
    4,096 virtual switch ports per host.
  28. At what level is a vSphere vNetwork standard switch configured?
    Host level.
  29. At what level is a vSphere vNetwork distributed switch configured?
    VMware vCenter Server level.
  30. What does a standard switch with teamed NICs provide?
    A NIC team provides automatic distribution of packets and failover.
  31. How can you view a host's standard switch configuration?
    You can view a host's standard virtual configuration by clicking the Networking link of a host's Configuration tab.
  32. What are the names of the virtual machine port group and VMkernel port that the ESXi installation creates?
    Virtual machine port group name = VM Network

    VMkernel port name = Management Network
  33. What are the names of the virtual machine port group and VMkernel port that the ESX installation creates?
    Virtual machine port group name = VM Network

    VMkernel port name = Service Console Port
  34. From the vSphere Client how can you display Cisco Discovery Protocol (CDP) information?
    The callout icon next to a physical adapter lists CDP information. Configuration tab > Networking link > Physical Adapters > click callout icon.
  35. Cisco Discovery Protocol (CDP) allows ESX/ESXi administrators to determine which Cisco switch port is connected to a given virtual switch. True or False?

    If False, Why?
    True.
  36. When Cisco Discovery Protocol (CDP) is enabled for a particular virtual switch, what Cisco switch properties can you view from the vSphere Client?
    • device ID
    • software version
    • timeout
  37. What are the Cisco Discovery Protocol (CDP) operational modes?
    • Listen
    • Broadcast
    • Listen and Broadcast
    • Diabled
  38. How you design your virtual network depends on many physical network considerations - name/describe five.
    • 1. Number of physical switches
    • 2. Network bandwith requirements
    • 3. Physical switch support for 802.3AD (for NIC teaming)
    • 4. Physical switch support for 802.1Q (for VLAN trunking)
    • 5. Network port security
